Paul does not attempt to describe the future body, but contents himself with pointing out one or two of its characteristics by which it is distinguished from the body we now wear. "It is sown in corruption; it is raised in incorruption: it is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power: it is sown a natural body; it is raised a spiritual body." In this body there is decay, humiliation, weakness, a life that is merely temporary; in the body that is to be decay gives place to incorruptibility, humiliation to glory, weakness to power, animal life to spiritual.
The present body is subject to decay. Not only is it easily injured by accident and often rendered permanently useless, but it is so constituted that all activity wastes it; and this waste needs constant repair. That we may constantly seek this repair, we are endowed with strong appetites, which sometimes overbear everything else in us and both defeat their own ends and hinder the growth of the spirit. The organs by which the waste is repaired themselves wear out, so that by no care or nourishment can a man make out to live as long as a tree. But the very decay of this body makes way for one in which there shall be no waste, no need of physical nourishment, and therefore no need of strong and overbearing physical appetites. Instead of impeding the spirit by clamouring to have its wants attended to, it will be the spirit's instrument. A great part of the temptations of this present life arise from the conditions in which we necessarily exist as dependent for our comfort in great measure on the body. And one can scarcely conceive the feeling of emancipation and superiority which will possess those who have no anxiety about a livelihood, no fear of death, no distraction of appetite.
The present body is for similar reasons characterized by "weakness." We cannot be where we would, nor do what we would. A man may work his twelve hours, but he must then acknowledge he has a body which needs rest and sleep. Many persons are disqualified by bodily weakness from certain forms of usefulness and enjoyment. Many persons also, though able to do a certain amount of work, do it with labour; their vitality is habitually low, and they never have the full use of their powers, but need continually to be on their guard, and go through life burdened with a lassitude and discomfort more difficult to bear than passing attacks of pain. In contradistinction to this and to every form of weakness, the resurrection body will be full of power, able to accomplish the behests of the will, and fit for all that is required of it.
But the most comprehensive contrast between the two bodies is expressed in the words, "It is sown a natural body; it is raised a spiritual body." A natural body is that which is animated by a human life and is fitted for this world. "The first man Adam was made a living soul," or, as we should more naturally say, an animal. He was made with a capacity for living; and because he was to live upon earth, he had a body in which this life or soul was lodged. The natural body is the body we receive at birth, and which is suited for its own requirements of maintaining itself in life in this world into which we are born. The soul, or animal life, of man is higher than that of the other animals, it has richer endowments and capacities, but it is also in many respects similar. Many men are quite content with the merely animal life which this world upholds and furnishes. They find enough to satisfy them in its pleasures, its work, its affairs, its friendships; and for all these the natural body is sufficient. The thoughtful man cannot indeed but look forward and ask himself what is to become of this body. If he turns to Scripture for light, he will probably be struck with the fact that it sheds no light whatever on the future of the natural body. Those who are in Christ enter into possession of a spiritual body, but there is no hint of any more perfect body being prepared for those who are not in Christ.
